TIVIE-CONTROLLED APPARATUS.

Application filed April 6,

To all whom t may concern Be it known that l, BRUNO BRAULT, a citizen of the United States, residing at Two Rivers, in the county of Manitowoc and State of Wisconsin, have invented certain new and useful Improvements in Time-Controlled Apparatus, of which the following is a specification.

This invention relates to controlling devices operative by time indicating means, such as an alarm clock, and has for one of its objects to provide a device of this character of improved construction and increased eliiciency. Y

l.Vith these and other objects in view the invention consists in certain novel features of construction as herein shown and described and then specifically pointed out in the claims.

The improved device may be employed for controlling the movement of various devices such as the dampers of heating apparatus, the feed boxes in stables, releasing the water supply for lawn sprinklers, opening the doors of chicken coops and the like, but is more particularly applicable to the opening and closing of the drafts of furnaces and the like, and for the purpose of illustration is shown thus applied, and in the drawings illustrating the preferred embodiment of the invention,-

Figure 1 is a side elevation of a conventional hot air furnace with the improvement applied and arranged to control the draft and check dampers of the same. v

Figure 2 is an enlarged side elevation, partly in section, of the alarm controlling portion of the improved device.

Figure 3 is an enlarged end elevation, and

Figure 4 is an enlarged side elevation, of the winding drum.

Figure 5 is a plan view partly in section, of the Winding drum.

The improved device includes a supporting bracket comprising a platform 10 adapted to be attached to any suitable support, for instance a wall indicated at 11 adjacent to the furnace whose draft is to be controlled.

The body of the furnace is represented as a Whole at 12, the intake draft door at 13, the smoke outlet flue at le* and the check 1923. Serial No. 630,295.

Vdraft damper or door at 15, these part-s wound up androtates reversely in the usual manner while the alarm is being sounded.

The stem 19 is provided with the usual wing key indicated at 2O by which the stem is actuated.

Rising from the platform'lO is a standard 2l having an offset 22 at the upper end terminating in a hook 23 to engage the holding ring 24 of the gong 25 of the clock. The

standard 21 with its hooked offset 22, coactsy with the platform 10 and holding member 17 to firmly support the alarm clock in position and prevent its displacement.

The standard 21 is firmly connected to the wall 11 by bolts 26.

A stud 27 extends from the ,standard 21, and mounted for rotation on the stud is a winding drum 28 having transverse open slots 29 in one end to receive the wings of the key 20. The drum 28 is provided with spaced encompassing ribs 30 to form guides to a Winding cable.

By this means the drum 28 is rotatably supported in place and coupled to the Winding stem 20, so that when the alarm sounds the retrograde movement of the stem 2O will be communicated to the winding drum.

Located at some convenient point on the Hoor, indicated at 32, in which the register 33 of the furnace 12 is located, is a pulley indicated at 341 associated with a graduated dial 35 and a pointer 36. A pull cord or cable 37 is attached at one end to the drum 28 and is conducted thence around a pulley block 38, the latter coupled by its frame 39 to a pull member 40 connected to the draft door 13 of the furnace.

Leading upwardly from the upper side of the frame 39 is another pull cable 41 which leads thence over the pulley 341' of the indicator dial 35, and thence around guide pulleys l12 to the check draft door 15 to which it is attached at 113. rEhe pull cable 37 is conducted upwardly from the guide pulley 38 to a fastening device 44 attached to the cable 4l between the indicator guide pulley 34 and the first guide pulley 42.

The intake damper 13 is initially closed vand the check damper 15 initially opened when the alarm mechanism is wound up, and is thus arranged at night or at other times. Then when the alarm is released at a predetermined time, for instance in the morning, the retrograde movement of the key member 19-20 will impart rotary motion to the drum 28 and wind up the cable 37 thereon and correspondingly impart motion to the cable 41 and thus open the draft door 13 and permit the check draft door 15 to close by gravity. `This movement of the cable 41 will cause the indicator 36 to denote the exact relative locations or positions of the doors 13 and 15.

The improved device is simple in construction, can be readily adapted to various structures as above noted. Y

The drum 28 is shown provided. with a `plurality of the slots 29 to enable the drum to be coupled to various forms and constructions of winding stems.

The preferred embodiment of the invention is disclosed in the drawings and set forth in the specification, but it will be understood that modifications within the scope of the claimed invention may be made in the construction without departing from the principle of the invention or sacrificing any of its advantages.

Having thus described the invention what is claimed as new is:

1. The combination with a furnace including a draft door, and a check valve, of an indicator device, a main cable connecting the draft door, the check valve, and the indicator, a timing device, a guide pulley at the end of the portion of the main cable between the indicator and the draft door, and a secondary cable coupled at one end to the portion of the main cable between the check valve andthe indicator and leading around the guide pulley and connected at the other end to the timing device.

2. The combination with a furnace including a draft door, and a check valve, of an indicator device, a main cable connecting the draft door, the check valve, and the indicator, a timing device, a winding drum coupled to the timing device, a guide pulley at the end of the portion of the main cable between the indicator and the draft door, and a secondary cable coupled at one end to the portion of the main cable between the check valve and the indicator and leading around the guide pulley and connected at the other end to the winding drum of the timing device.

In testimony whereof, I aHiX my signature hereto.

BRUNO BRAULT.
